APOSTOLOS C. IIHOJYIITIS, OF RAYMOND, NA-SHINGTON.

nu'roiaarro PISTOL.

Application filed March 27, 1922.

To zZZ whom it" may concern.

Be it known that I, Aros'roLos CHRIS- TorrirLos Iri-roMiTis, a citizen of Greece, but who have declared by intention to become a citizen of the United States, and resident of the city of Raymond, in the county o't Pacific and State of Washington, have invent-ed new and useful Improvements in Automatic Pistols, of which the following is a specification.

h Iy invention relates to improvements in automatic firearms, and the objects of my invention are to provide means whereby the recoil of the explosion shall furnish energy for ejecting the empty cartridge, reloading, and firing the new shot. Special objects of my invention are to provide an improved trigger mechanism and an improved magazine for cartridges.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure I is a vertical section of the pistol; Fig. II, an elevation with the front half of the casing removed to show the cartridge magazine in place; Fig. III, a plan view showing the recoil chamber; Fig. IV, a sec- .tional view of the magazine; Figs. V, VI and VII, are enlarged views of the trigger mechanism; Fig. VIII, a side view of the entire pistol; Fig. IX, a horizontal section, showing manner of ejecting a cartridge; Fig. X, a cross section on line AA; Fig. XI, and XII, are cross sections on lines BB and CC Fig. XIII, a rear view of the bolt Fig. XIV, a horizontal sectional view of the bolt; Fig. XV, a vertical sectional view through the magazine and pistol; Fig. XVI, a front end view of the bolt; and Fig. XVII, a side elevation of the bolt.

The numeral 1 designates the stock of the pistol, 2 the barrel, and 3 a cartridge within. Within the casing 5, is a chamber 6 for the trigger mechanism, and a chamber 7 for the cartridge magazine. To the rear of the barrel 2 and in axial alignment therewith is a breech-chamber 8, and lying parallel thereto a recoil chamber 10. In the breechchamber 8 is a bolt 12 designed to reciprocate therein, and provided with an arm 34 extending through a slot into the recoil chamber 10. A compression coil-spring 35 is mounted between studs in this chamber and serves to absorb the recoil of the explo- Serial No. 547,219.

sions upon said bolt and to cause the latter to rebound to tire the nest successive charge.

An arm 30 extends horizontally through a slot-43 in the side wall of the pistol-limeech through which the bolt be manipulated by hand. Said bolt is termed with an interior chamber 21 to receive a firing pin 11.. A coil spring 1%: lies within this chamber in such a way as to urge the pin forwardly. The front end of the tiringpin protrudes through the walls of chamber 21 so as to strike the tl ulniinating cap of the .;artri lgo 3.

A trigger 19 is pivoted within the chamber 6 and connected to said trigger is a finger with segments 16 and 17. A coil spring 20 tends to pull this finger forward in an upright position, and a fiat spring 18 tends to hold the uppermost segment 16 in alignment. Upon aprojection of segment 17 rests one end of the lever 15. The other upturned portion of the lever projects into the breechchamber 8 and engages the head of the firing pin 13 upon its rebound. The segment 16 also projects in the path of the head of the firing pin.

The pistol is provided with a detachable magazine 33 for cartridges. Within this magazine is a fiat folded spring 23 support ing a pan 41 upon which in superimposed order lie the cartridges 21 and 22. The pan 11 is provided with an arm 31 which extends horizontally through a slot 32 in the wall of the magazine 25 by means of which the pan may be depressed for filling the magazine. The magazine may be removed or inserted by means of a hinged plate 46 at the bottom of the casing 29.

An extractor 4-2 pivotally connected to the bolt 12 is so arranged as slightly to project and seize the rim of the cartridge and withdraw it until the opposite edge of the rim strikes upon the pin 417. At the impact the cartridge is thrown out through opening 48 as shown in Fig. IX. A slot 49 in bolt 12 accommodates the passage of the bolt by said pin.

The operation of the gun is as follows:

A cartridge being in position, as shown in Fig. I, the bolt is cooked by pulling back the bolt by means of arm 30 until the lug 13 is engaged by the dog 15. As said arm is released the power of spring 35 forces the bolt forward in the breech-chamber, but the firing pin is retained by the dog 15, and in this manner the Pulling ti... tri which the against the plodes it.

Pulling the tri {er 19 raises the rear end of the lever auo. l until the lug is disengaged and the iris!"- pin released. Upon the recoil oi" the after the shot. the lung 13 pushes l'vaclr the I thereby releasinp the lever 11) the notch in the earment l7. lever is then torceo. u ward b its spring 50 so to the head 1 firing pin 13 as ltietore. With its bac motion the lug; 13 releases the lever by pushing back the finger l6. but upon the tora'v rd motion spring; 18 allows the tip 16 to be. d iliorwar'd until the lug ha. passed h [l'he next shot is fired by releasing the fin. trigger 19, and so allowin the segment 1.! to drop down until its nitch reengages the lever 15, whereupon pulling the again fires the pistol.

As one cartridge ejected the storing forces up another into its place. and the bolt forces it forward into the shel v chamber.

The automatic pistol is simple of construction. accessible to inspection and repair. and automatic in action, yet at all times under trigger control. A plate of 28 covers metal. the rear portion of slot 40 and serves to make the weapon dust proof.

In my application No. 519.830. filed Dec. 5th 1921. I have shown a firearm with some of the same features appearing); in the automatic pistol.

I claim:

1. In an automatic firearm. a trigger. two sections pivotally connected therewith. a spring tending; to keep said. sections in an upright position a flat spring tending to keep the second section in alignment with the first, and a sear controlled by said trigger and sections.

2. An automatic pistol includinga barrel. a breech-chamber in axial alignment therewith and a recoil. chamber parallel with said breech-chamber. a chambered bolt formed with an arm extending in said recoil iuber. a compression-spri11g in said recoil chamber arranged to exert its torce upon said bolt through s id named arm. a firing pin mounted in the chambered portion of said bolt and provided with :1 lug at its rear end exteriorly of the bolt. a coil spring tending to urge said pin forwardly. a trigger having an upturned finger yieldingly connected thereto, said finger composed of two sections. a spring drawing the finger forward. a second springholding: the top section in alignment with the lower section, and a sear controlle by said finger. an extractor on said bolt. a pin in the path of the shell being ejected, and upon the side opposite the extractor to act as stop and a fulcrum to eject the shell. a magazine having an opening in the side and detachable from said pistol means for retaining said magazine Within the pistol, a fiat bent spring retained in said magazine. a plate above said spring); an arm aflixed to said. plate and extending through said opening.

In testim ony whereof I my signature in the presence of two witnesses.

A. ITHOMITIS.
